SPRAY NOZZLE.

Application filed April 4,

To all ."zgizom a mrn f concern:

Be it known that I, HARRY H. Bunions, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented certain new and use ful improvements in Spray Nozzles, of which the following is a specification.

This invention relates to new and useful improvements in nozzles for liquid spray guns.

The primary object or" my invention is to provide a nozzle for discharging liquid in the form of a spherical spray. The device is especially adapted or valuablefor applying liquid carbon removers to the cylinder heads and combustion chambers of internal combustion engines, but may be'used with equal facility in a number of other instances, as will hereinafter appear.

In the accompanying drawings," which are for illustrative purposes only and are therefore not drawn to scale Fig. l is a side elevation, illustrating the application of my invention to a spray gun.

Fig. 2 is an enlarged side view of the nozzle and a portion of the nozzle pipe.

Fig. 3 is a front end view of the nozzle.

Fig. 4 is a view of the nozzle pipe and nozzle, with the outer end of thenozzle pipe and the nozzle shown in section.

Fig. 5 is a vertical transverse section, taken on line of 4t, lookingin the direction indicated by the arrows and Fig. 6 is a detail end view of the strainer.

Referring to the drawings for a more particular description of the invention and in which drawings like parts are designated by like reference characters throughout the several views, A represents a spray gun,

(shown in dotted lines) B the nozzle pipe and C my improved nozzle, as a whole.

The nozzle C, which is of general spherical for is constructed in four separate parts 1, 2, 3 and 4, respectively. The four parts or sections thus forming the nozzle, fit on the outer end of the nozzle pipe B, which is provided with one or more transverse ports or apertures 55 for the egress of the liquid. As shown, the meeting faces of the nozzle sections are formed with small registering radial grooves for the discharge of the liquid, which is ejected in the form of a spherical spray.

The nozzle pipe 13 is provided near its outer end with an exterior thread 7, on

raritiewhich the inner section 1 of nozzle screws and is slightly reduced from the outer end of said threaded portion to its outer end. The extreme outer end of said pipe is also exteriorly threaded, as atF8, for

screw threaded engagement with the outer nozzle section 4', which, when screwed into,

place, holds the four parts or sections form-Y ing the nozzle together as one unit;

A cylindrical strainer 9 of wire gauze or other reticulated material surrounds the apertured partsof thenozzle pipe within the annular chamber 10 to collect any sediment that may be in the liquid and might.

otherwise stop or clog up the groovesrt'.

The front end of the nozzle is provided with a iorwardly projecting mouth 11 formed with the outwardly flared side walls 12 and the small centrally and longitudinally disposed slit 13 for the discharge of the liquid.

--Among the many advantages that may tion, some of the more important may be.

and cylinders of internal combustion engines. 1 I

-Th1rd: It is valuable in cleaning ;or

sterilizing milk bottles or in applying any liquids where a spherical spray isneeded. Fourth: It is especially valuable where tiny outlets are needed in sphericalspray nozzles to economize in the use of the liquid. as it permits of easy accessibility to clean.

Fifth: Permits the use of fine mesh strainers in small as well as large nozzles to collect anysediinent that might otherwise clog or stop up the discharge passages.

From the foregoing description taken in, connection with the drawings, it is thought that the construction, operation and advantages of this invention will-be readily understood without requiring a more extended explanation.

Having describedmy inventionpwhat 1 claim asnew and desire to secure-by Letters Patent, is

1 A spherical nozzle comprising a plurality of separable sections formed intheir meeting faces with small registering radial grooves, said nozzle adapted to discharge liquid through said grooves in the form of spherical spray.

2. In combinetionwith enozzle pipe. s herlcel" nozzle "formed of e olurahi'v ol I 1 a 1 sepereble sectlons formed in their meemng faces with small registering radlelgrooves,

' the inner and outer nozzle sections having screw threaded "engegement "with said )ipe.

- In combination with a nozzle pipe provided near-its outer end with "a' plurality of transverse d scharge ports spherical noztured portion of said nozzle pipe, the inner end" outer nozzle sections having screw threaded engagement with the nozzle pipe. In testimony whereof I affix my signeture.
